White roses, large white flowers with high centers and curled edges, beautiful flower shape, stiff and thorny pedicels and branches. The grading standards are: first grade, above 45cm, with full flower buds, thick branches, dark green leaves, and no pests or diseases. Second level, 30-45cm, with full flower buds, thick branches, dark green leaves, and no pests or diseases. Level three, less than 30cm, with smaller flower buds, thinner branches, slightly variegated leaves, and no pests or diseases. White roses like sunshine, are relatively cold-resistant, drought-tolerant, and like ventilated and cool climates. The suitable growth temperature is 15-25 degrees. Roses have strong adaptability and are not strict with the soil. They grow well in fertile neutral or slightly acidic light loam soils and have many flowers. Botanical white roses are more cold tolerant than white roses.
